Vuam yog kev kos duab ntawm cov hlau thiab lwm yam khoom siv ua ke.Nws kuj muaj cov khoom xws li kev tsim kho thiab kev tsim khoom.Vuam tuaj yeem ua haujlwm tau txais txiaj ntsig, tab sis koj yuav tsum paub ob peb yam sib txawv ua ntej koj ua tiav koj lub hom phiaj xav tau.Yog tias koj xav dhau los ua tus kws tshaj lij hauv kev lag luam hlau, ntawm no yog tag nrho cov ntaub ntawv koj yuav tsum paub txog yuav ua li cas los ua tus welder.
Muaj ntau hom vuam, tshwj xeeb hauv kev sib txuas cov khoom sib txawv.Cov hauv qab no yog peb txoj kev siv vuam ntau.
Hom vuam no qee zaum hu ua qws vuam, thiab nws siv tus pas nrig lossis electrode uas tau noj los ntawm lub vuam teeb.Hluav taws xob yog lub hauv paus ntawm lub hwj chim.Nws yog siv los tsim ib qho arc nruab nrab ntawm cov hlau nto thiab cov electrode, thiab cov electrode molten yog siv los ua ib tug muab tub lim rau lawv ua ke.Hom vuam no muaj ntau heev hauv kev tsim kho thiab lwm yam kev lag luam hnyav vim nws yog siv los koom nrog cov hlau loj.
Qhov no yog qee zaum hu ua hlau inert gas (MIG) vuam, thiab nws txoj haujlwm ua haujlwm yuav luag zoo ib yam li cov pas nrig vuam.Nyob rau hauv rooj plaub no, qhov sib txawv tsuas yog siv cov xov hlau txuas txuas txuas ntxiv tsis siv cov pas nrig.MIG vuam yog muaj nyob rau hauv kev tsim thiab automotive industries.Qhov tseem ceeb tshaj, txoj kev vuam no yog huv dua li kev siv vuam bar.
Hom vuam no tseem hu ua Tungsten Inert Gas (TIG), uas hloov cov khoom siv hluav taws xob los yog hlau siv hauv MIG lossis qws vuam.Hloov chaw, nws siv cov tungsten uas tsis yog siv tau, uas txhais tau tias tsis muaj cov khoom siv muab tub lim.Lub tshav kub generated los ntawm arc melts cov hlau nto, tsim ib daim ntawv cog lus.TIG yog daim ntawv yooj yim tshaj plaws ntawm vuam, tab sis nws kuj yog qhov kev xaiv qeeb tshaj plaws.Hom vuam no feem ntau yog tsim rau cov hlau precision uas nws cov tsos yog qhov tseem ceeb.
Yog tias ua tib zoo npaj, vuam yog ib txoj haujlwm muaj txiaj ntsig uas tuaj yeem muab ntau txoj hauv kev hauv ntau qhov chaw.Muaj ob peb kauj ruam uas koj yuav tsum tau ua kom mus nrhiav haujlwm ua ib tug welder, thiab hom vuam koj xav ua yog txiav txim siab koj qhov kev kawm.Koj tuaj yeem tau txais ob qho ntawm ob qhov kev lees paub feem ntau hauv Tebchaws Meskas los ntawm kev kawm qib siab lossis kev cob qhia ua haujlwm raug cai.Cov no suav nrog American Petroleum Institute (API) thiab American Welding Association (AWS).
Txhawm rau mus nrhiav haujlwm hauv vuam, koj xav tau daim ntawv kawm tiav high school lossis sib npaug los kawm cov kev kawm uas koj nyiam.Kev kawm hauv tsev kawm ntawv theem siab yog qhov tseem ceeb vim tias nws muab cov kev kawm yooj yim, xws li algebra thiab geometry, uas koj tuaj yeem siv los nkag siab tias cov ntaub ntawv sib txuas ua ke thaum lub vuam txheej txheem.Lwm lub tsev kawm ntawv theem siab muaj cov kev kawm vuam los npaj cov neeg sib tw rau kev xeem ntawv pov thawj vuam.Yog tias koj xav sawv tawm hauv chav kawm vuam, kev cob qhia thiab kev kawm yog qhov tseem ceeb.
Muaj ob qhov kev lees paub tseem ceeb, suav nrog American Welding Society thiab American Petroleum Institute.API yog qib siab dua thiab feem ntau tsom rau kev lag luam petrochemical.Yog tias koj tshiab rau vuam, koj tuaj yeem txiav txim siab siv AWS.Nws yuav siv li ob peb lub lis piam lossis xyoo rau koj kom tau txais daim ntawv pov thawj vuam uas koj npau suav txog.Yog tias koj tsis muaj kev kawm txuj ci, yog tias koj xav tau daim ntawv pov thawj API, koj xav tau kev paub ua haujlwm.
Kev xyaum ua haujlwm yog txoj hauv kev txhim khu kev qha los pib koj txoj haujlwm vuam.Ntau lub tuam txhab muaj kev cob qhia ua haujlwm, qhov chaw koj tuaj yeem tau txais kev paub dhau los thiab tau txais qee qhov nyiaj pub dawb thaum ua haujlwm nyob rau hauv kev saib xyuas ntawm cov kws paub txog vuam.Koj yuav tsum tau xyuas cov kev cai rau kev thov rau kev xyaum ua haujlwm.Koj yuav tsum nrhiav qhov chaw xws li tsoomfwv cov vev xaib thiab cov tsev kawm haujlwm ua haujlwm kom tau txais kev xyaum ua haujlwm.Yog tias muaj ib lub koom haum vuam hauv cheeb tsam hauv koj cheeb tsam, koj kuj tseem yuav tau txais kev xyaum ua haujlwm.Kev cob qhia muaj ntau yam zoo vim tias vuam yuav tsum tau xyaum ntau dua li kev xav.Qhov tseem ceeb tshaj plaws yog tias koj khwv tau nyiaj thaum koj kawm.
Vuam yog txheej txheem uas koom nrog cov hlau thiab lwm yam khoom siv los tsim cov qauv sib txawv.Raws li koj tau pom, feem ntau muaj peb hom vuam, uas yog siv rau ntau lub hom phiaj.Yog tias koj xav ua ib tug welder, koj yuav tsum xub xaiv hom vuam uas koj xav tau tshwj xeeb hauv kev kawm theem siab yog qhov tseem ceeb vim nws muab koj cov kev paub tsim nyog rau kev ua haujlwm vuam.Yog tias koj xav kom tau txais kev tsim nyog, koj tuaj yeem xav txog cov txheej txheem vuam sib txawv.
